Course Icons

In each course on this site, certain sections of text are highlighted to assist your understanding of the relevant content. Each of these sections is marked with an icon that depends on what type of content is present:

Warning - These text boxes let you know that what you're doing has the potential to cause issues if the instructions are not carefully followed. You may be told about common errors and how to avoid them, or you may be told how to recover from a problem if it occurs.
